[cisco-voip] ISDN data calls over H.323?

[Vincent De Keyzer]

Yes, that could be a solution, but it means that I have to know it in
advance (and sometimes they just won't tell me - don't ask why).

All I would like the Cisco to do is transparently pass on the call to the
CPE: if it's a data call, set up a data call; if it's a speech call, set up
a speech call.

Am I the only one facing this problem?...

Vincent
